Is he groundbreaking?
No, certainly not. Half the time (while singing live) he doens't use his falsetto voice and just drops down into the octave or two octaves below for the notes. This is disappointing because he doesn't express anywhere near the emotion on the lower notes that he does on his high notes. He's playing it safe, which, overall might lead to low risk, but it isn't impressive.

Is it bad that he's your idol?
If you like his songs and if you agree with what they stand for then no.
